Out pop star Adam Lambert has a birthday coming up. And David Arquette's gift was on display via social media Saturday night.

The actor apparently stripped down to his underwear and gave Lambert a lap dance while they were celebrating at Bootsy Bellows in Hollywood.

Actor Collin Owens shared one of the photos. And jewelry designer Markus Molinari, who is a partner in the club, posted, "I hope u’ll be bringing out the #CHAMP 4 my birthday like u did fur @adamlambert at @bootsybellows #lastnight" It wasn't long before the photos showed up on blogs, including Socialite Life.

Lambert himself shared a photo with Arquette in his lap, saying dryly, "Yup... this happened."
